Here is a recent application in which our experiment and the assets of our flowmeters made the difference.

100 points of flow measurements on the largest hidroelectric powerstation in the world: Itaïpu

We are proud of having won, via our subsidiary company USE, the flow measurements market of the cooling circuits of the 20 turbines of the largest hydroelectric power station in the world.
Let us recall that this power station is fed by the dam named Itaïpu, one of the seven wonders of the world. Located on the Paraná river, cross-border between Brazil and Paraguay, its capacity of 14.000 MW exceeds still today that of the Three Gorges dam in China. It ensures nearly 89% of the power consumption of Paraguay and 25% of the total of the Brazilian market demand. When the 14 valves are opened, nearly 62.200 m³/s flow in rumble. The 20 turbines able to manage 700 m³/s of water each, are surrounded by a cooling circuit under high supervision. More than 100 ultrasonic flowmeters of our MINISONIC range (fixed version and a portable device) are installed to take care of the flow regulation. The pipes diameters ranging from 1”½ to 18“ are equipped with our clamp-on probes which are easy to install, without drilling the pipes and pressure loss. The accuracy of these flowmeters, proven by an independent calibration laboratory lies between 0.5% and 1%.Some meters, chosen as sample and COFRAC certified, show a 0.1% repeatability.
